“Vegetables should be high-yield, and good varieties are the key.†What problems should farmers pay attention to when purchasing vegetables?
1. Try to buy seeds from large-scale, reputable seed companies and research institutes. Seeds sold by some small, unfamiliar business units should be carefully purchased, especially if they are cheap to buy at the market.
2. When a lot of seed companies conduct product promotion, they often emphasize their advantages on a one-sided basis, avoiding the disadvantages of flashing their words, and not explicitly explaining their adaptation to the planting area. Therefore, we should try to use local varieties that have better performance and planted for many years. For example, if we change new varieties, we should first try small-scale trials, and then expand the area after accumulating experience. Do not blindly introduce large areas, and we must not believe in the falsehood of the sales units. Promotion.
3. When planting carrots, spinach, onions and other vegetables for export, it is necessary to purchase imported seeds as much as possible, because the varieties of such seeds meet the requirements of foreign consumers, while the domestically produced vegetable seeds are lower in price, but the produced goods are produced. Does not necessarily meet export requirements and may affect sales.
4. Pay attention to the geographical latitude when purchasing or introducing seeds. Most vegetable seeds should be introduced at the same latitude. For example, many bean cultivars from the southern part of the country are introduced into the north. Due to the prolonged sunshine duration, the growth and development are strong, resulting in delayed pod formation and reduced economic benefits. The onion varieties originating in the north, Introduced into the southern region with short sunshine, the growth is strong, but the bulb yield is not high. After the introduction of southern onion varieties in the north, the growth period is significantly shortened and the bulbs are greatly reduced. Although most new varieties are not strict with sunshine time, they should be noted when introducing.
5. In order to alleviate the harm of garlic virus, many vegetable farmers have taken different places. Try to change from the northern region when changing varieties, because the north is colder than the southern summer, and the virus disease is relatively light. In addition, detoxified garlic can also be used for seeding (but at a higher price).
6. Domestically sold vegetables should pay attention to consumer demand. For example, in the northern region, the top flower is thorny cucumber, and in the east, the red onion is preferred. When planting, the corresponding vegetable variety should be purchased according to the market demand of the place of sale.
7. Vegetable seeds have a short shelf life. For example, green onions, onions, and leeks lose their vitality after one year of storage. The best use period of seeds is 1 to 2 years. Therefore, pay attention to the date of manufacture when purchasing seeds, and do not purchase expired dishes.
8. Ask for the invoice and keep it in a safe place. If there is a quality problem, make a timely claim to the sales unit.
